ELLIGOTT D. AVERELL, OF NEW YORK, N. Y. Letters Patent No. 60,663, datedJanuary 1'3'1867.

IMPROVEMENT IN RULIN G PAPER BY ELEGTRO-MAGNETISM.

TO ALL WHOM IT MAY CONCERN:-

Be it known that I, ELLICOTJ. D. AVERELL, of the city of New York, inthe State of New York, have.

invented a new and improved mode of Ruling Paper by the aid ofElectro-ldagnetism; and I do hereby declare that the following is a fulland exact description thereof, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon, v

The nature of my'invention consists in the fixing of an electro-magnetat one end of a pen-boardof the ordinary ruling machine, having attachedthereto an armature, in combination with the circuit-breaker fingerdescribed in my Letters Patent dated June 12, 1866, No. 55,594. Thewires surrounding the magnets are connected with fingers attached to themechanism in such manner as will be moved by the paper passing over theendless cloth or other band, and when moved, to open or close anelectric eircuit composing the surroundings of.

the ,elctro-magnet bobbins or spools. When the paper passes with theendless band, it moves the finger, which, acting as a key to theelectric circuit, opens or closes the circuit. around theelectro-magnets, and at that moment magnetizes the cores of the saidmagnets, which immediately attracts the armature attached to thepen-board, and then the pens mark the paper as desired. The mechanismrequired to open and close the electric circuit is embraced. in myPatent No. 55,594 for an improvement on ruling machines.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation; the said inventionbeing an improvement on my Patent No. 55,594.

I construct my eleptro-magnet similar to those used for telegraphicpurposes; but the armature is attached to a board carrying one or morepens, such as are used in the ordinary ruling machines in bookbinderies. The electro-magnet, when acted upon by a current ofelectricity, attracts the armature carrying the pens down upon thepaper, and, when uncharged, a spring carries the pen-board up from thepaper. The charging and uncharging thew'rire surrounding theelectro-magnet is done by a circuit-breaker operated upon by contactwith the sheet oi paper to be ruled.

Figure lrepresents a view of the machine complete.

A is the electro-magnet, B the armature carrying the pen-board, C;thecarrying band; E E conveys the paper to be ruled, which strikes againstthe circuit-breaker finger at F, which closes the circuit at G, and thuscharging the wire around the electro-magnet A, causing the armature, B,to descend, bringing the pen-board down'so as to allow the'pens tostrike the paper.

Figure 2 is an enlarged view of the circuit-breaker and contact finger.

Having "any described the nature of my invention, and the mode ofoperating it, what I desire to secure by Letters Patent, isg g Iclaim-the application of an electro-magnet for the purposes of rulingpaper, in combination with the circuitbreaker finger F, in the mannerand substantially as described in the foregoing. v
